Question 1

What is Follow the Chain?

Accepted Answer

A mechanical-reasoning streak game. You trace a chain of gears or logic gates from a known starting condition and determine the final output. One wrong answer ends the streak.

Question 2

What are the two modes?

Accepted Answer

Gears (trace a gear train to find which direction the last gear rotates given the first) and Circuits (trace AND, OR, XOR, NOT, and NAND gates given input signals to find the output).

Question 3

What skill does this train?

Accepted Answer

Mechanical reasoning and deterministic rule-tracking · the ability to hold a sequence of transformations in working memory and apply each rule correctly. Used in engineering, programming, and systems thinking.

Question 4

How does difficulty scale?

Accepted Answer

Easy difficulty uses short chains with few components and clear visual labels. Higher difficulty adds more gears or gates, introduces additional gate types (NAND, NOR, XNOR), and removes labels so you must work from the diagram.
